Embodiment Construction

[0010]Referring to the FIG. 1, a plastic housing 10 of an exemplary embodiment includes a substrate 11, an activating metal coating 12 made of noble metal, a chemical metal coating 13 bridgedly deposited on the activating metal coating 12, an oxidized metal film 14 and an electroplated metal coating 16 both formed on the chemical metal coating 13, and a patterned ink coating 15 formed on the oxidized metal film 14. The substrate 11 may be made of material selected from the group consisting of acrylonitrile butadiene styrene (ABS), polymethyl methacrylate (PMMA), and polycarbonate (PC). The oxidized metal film 14 may be formed by oxidizing the chemical metal coating 13, but does not completely cover the chemical metal coating 13. The electroplated metal coating 16 is formed on a portion of the chemical metal coating 13 not covered by the oxidized metal film 14.

[0011]The patterned ink coating 15 may be applied by a printing process, preferably by screen printing, to display designs su...

Abstract

A plastic housing includes a substrate, an activating metal coating made of noble metal, a chemical metal coating deposited on the activating metal coating, an oxidized metal film formed on and partially covering the chemical metal coating, an electroplated metal coating formed on a portion of the chemical metal coating not covered by the oxidized metal film, and a patterned ink coating formed on the oxidized metal film. The patterned ink coating is recessed relative to the electroplated metal coating.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a method for making plastic housings.[0003]2. Discussion of the Related Art[0004]Electroplating is an attractive and effective process for improving corrosion resistance and metallic appearance of covers. Many covers for mobile devices are processed to form plated metal coatings on surfaces thereof using electronic plating.[0005]Designs as such pictures or patterns are typically made by printing ink on the covers. However, ink poorly adheses to plated metal coatings, thus ink can be worn away.[0006]Therefore, there is room for improvement within the art.BRIEF DESCRIPTION OF THE DRAWINGS[0007]Many aspects of the plastic housing can be better understood with reference to the following drawing. The components in the drawing are not necessarily to scale, the emphasis instead being placed upon clearly illustrating the principles of the present plastic housing. Moreover, in the drawing, like r...
